Long story short, we bought a 2010 F250 Powerstroke off of the insurance auction that was rolled by a member off of here from NY. It had a spartan tuner and also the dpf was removed etc. Anyway the truck ran good before we even repaired it, we found a cab and swapped it around using all the original interior, dash, wiring etc. We then sold the truck too a customer from WY. This all happened this spring. Anyway he drove it and put quite a few miles, took it too FL and back out west etc and he was really pleased with it. Said it got great MPG. Now he called back a month ago and said the truck is not working at all. When they turned the key the truck would not start and the dash had different readings etc.

So they took it too the dealer(no warranty of course) and first off we thought it was a bad ground and also maybe had something too do with the spartan tune. Ford reflashed the ecm back too stock just too make sure and also talked with a spartan tech and he thought it might be the PCM or the wire harness for the PCM. So they replaced that and the truck seemed too work fine for just awhile and then it started doing the same thing.

He then had the tech call me because the customer is still thinking that maybe it had something too do with the rebuild. Well it couldn't be because we used all the original wiring and there is really no way something could have gotten messed up. So we came to the conclusion it must be the ecm, so they replaced that and it still doesn't work. Sometimes the dash lights up when you turn the key and other times it doesnt.
It seems about like a dead horse but we really need too get this taken care of. The only thing I can think of is the ecm must be bad but that has been replaced so what else could cause this?? We are open too any ideas, as I will be talking too the tech in the morning.

Also Ford has flagged the vin because they have done all they can do according to the books I guess. The truck is currently at a Powerstroke specialist in FL.

Hopefully you can make sense of this story and would sure appreciate any help we can get

As stupid as this sounds, did you guys check the batteries? My truck is bone stock except for lighting and an auxiliary fuel tank, but when my truck started acting up the dealership initially told me that they couldn't find the problem. I started video taping my starts and played it to the tech, after which he took me into the work area and tested the batteries right in front of me. Guess what? One of the batteries was bad.

If it's a start problem, there's not a whole lot that can go bad with the truck. The schematics don't lie. I think you got yourself a chitty dealership.

Yes the batteries are fine. We got the truck here now in IA and when the trucker brought it, he actually started it right up and drove it off. It runs fine but when you drive it down the road it only shifts through a couple gears. Also the dash has a bunch of different lights on etc, like there is a bad ground. Haven't got started on it yet but I'm really at loss where too even start as the tech seemed too have covered his bases pretty well but obviously he missed something. Any more ideas??

Hmm well thats what it seems like but when the dealership tried too program the new ecm they weren't able too, so the old one is on currently. Guess it could also be a shorted wire somewhere but where too go about looking for it not sure??

I'll have too check that. Also I noticed that there is some condensation around some of the fuses on the fuse block, looked like some water got in there, does it ever happen where a fuse block goes bad but then it would hardly cause all those problems either then??
